Seven structural phases and ten associated sub-phases date between the IA I (phase 12) and the late IA III (phase 6). The earliest levels, from phase 12 (L.2319) to phase 9d (L.3202) were documented in a deep sounding, while the uppermost phases (8 to 6) were exposed over the entire surface of area G. Excavation of the earliest phases (12 to 9) in the deep sounding revealed an open space with superimposed pebbled floors. As works extended over the entire area (phases 8 to 6), some structures made of large stones, sometimes carved, were recovered.
